ServiceHost Class constructor

I'm refering the book Microsoft Windows Communication Foundation Step By Step. It says that

If you omit the base address information in the ServiceHost constructor, like this:

ServiceHost productsServiceHost = new ServiceHost(typeof(ProductsServiceImpl));

the WCF runtime will just use the 开发者_如何学Pythonaddress information specified in the application configuration file, and automatically listen for requests on all configured endpoints.

But when I try to declare the ServiceHost class using VS 2010, it gives only 2 option for ServiceHost class. Both of which need base url. Is above constructor removed in VS 2010 or am I missing something?

There are indeed two constructors:

• public ServiceHost(Object singletonInstance, params Uri[] baseAddresses)
• public ServiceHost(Type serviceType, params Uri[] baseAddresses)

However, note that they both use a params argument for the base addresses. This means it is valid to not pass anything at all.

Figured it out. It was missing the baseAddress element.
